What is the function used to output a certain character a certain number of times?

[furtivefelon]

try a loop?

1) Copy the character in an array - memset(void *str, int c, size_t n)
2) printf

nvm i found a faster less annoying way

[Chankama]

So care to tell us what is faster :eek: and less annoying :eek: than a single line
printf("...", memset(...) ) ?

printf("...", memset(...) ) that is in C not C++.

char theCh = '#';

for(int i = 0; i<9; ++i)
{
cout<<theCh<<endl;
}

Well the C commands works in C++. You can use <stdio.h> or <iostream> or whatever.

In anycase, using the cout << operator or the cout.put or printf function to output each character separetely in a LOOP is a terrible way of doing this. You are essentially calling a function each time to output one character. Not very robust at all. It's slow and looks ugly. This type of coding is good for a high school project, but that's about it..

So to output 1000 characters, u want to call the function 1000 times?? :eek:

If you want to use cout instead of printf,
cout << memset(...);

Still one line and only 2 function/operator calls ..

Did i call it 1000 times, no i don't think so. If he asked me to call it 1000 times i would have done it differently. Did he say it must be robust and efficient no. The question he asked was very simple so i assumed he is doing a simple project. So he would only have been taught a certain simple way. If i was a teacher and i saw a student that does not know how to ouput a character 7 or so times do what you did, i would suspect plagarism. Not all C++ students understand C.

Now if you want to convey an idea across to a student would you explain a clear simple way, or a way that offers no clarity? I think the best method is to explain how to do it easily(something you can see work) first and then show a more efficient method later.

Everyone knows that C code works in C++, C++ came from C it's kind of obvious. All programmers should know how to use memset anyway because it is very cool and works very efficiently.

  
#include <iostream>
using namespace std;

int main()
{
	char str[1000]= "";
	memset(str, '-', 1000);
	puts(str);
	
	return 0;
}

Yeah.. I think it's always nice when students start off learning C.. Even before Java and such. It's unfortunate that a lot of teachers don't stress the value of C. I mean, just to write a simple program in Java, you need to teach them objects, member functions, etc. etc.

Yeah all the universities jumped on the Java and C++ band wagon and now they are realizing their mistake. My professors say that if they could choose they would go back to C and would also teach Fortran, i think they will soon. Every engineer should still learn Fortran and Cobol because there is a ton of code out there that business's don't want to replace. Plus there are some cool stuff that you can teach in C that isn't in C++.
